There seems to be an agreement to include GLPK, but as I noted elsewhere, the package does not build properly on 64-bit Solaris, as the right compiler flag (-m64) does not get added. Robert created a ticket for this.

The spkg-install and SPKG.txt are a bit odd, so I'm trying to sort them out.

SPKG.txt says:

---------------------------------------------------------
== License ==

The GLPK package is part of the GNU project, released under the aegis of GNU.
----------------------------------------------------------

but src/COPYING is clearly GPL 3

                    GNU GENERAL PUBLIC LICENSE
                       Version 3, 29 June 2007


Are GPL3 packages allowed as standard, rather than just optional? I thought there were a no-no.

Assuming the license is not an issue, is there a reason to use version 4.42, when 4.44 is the latest? (Both versions are GPL 3).
